COMBINED STAPLE AND DIE.

. SPECIFICATION forming part of Letters Patent No. 293,540, datedFebruary 12, 1884.

Application filon November e1, 1883. (No moda.)

' and useful Improvements in Combined Staples and Dies and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had manufacture.

- angles with the former staple.

My invention further consists in combining two of saidstaplesto producea fastening for attaching together papers, fabrics, or other analogousmaterial or articles, whereby the prongs of one ofthe staples areinserted through the material from the upper side thereof, and the otherstaple being inserted from the under or opposite side of the material,but at right The prongs of both staples are n'ow pressed toward eachother by suitable means, when the points thereof, coming each in Contactwith the deiiectingdies wrought in the base of its fellow staple, areforcibly clinched thereunder, thereby producing a very attractive,simple, and inexpensive fastener, all as will be more fully hereinafterset forth.

In the accompanying sheet of drawings, Figure l represents (enlarged) avertical central'section through my improved staple when used as afastening.- Fig. 2 represents a side view of the staple. Fig. 3represents an inverted plan view of the blank from which the staple isformed. Fig. 4L represents a central section through the staple on linex of Fig. 3, showing the prong-detlecting dies therein.

A represents, in the drawings, my improved Astaple, so-called, having ahead or table,

A', into which is formed or wrought the dies or detlectors a, the latterbeing enlarged or widened at the outer edge of the table. Said staple isfurther provided withl the prongs a. At a, (see Fig. 3.) adjacent to theprongs, the head is cut away slightly, whereby the edge of said head A',&c., is adapted to project be youd the prongs. (See Figs. l, 2.)

I am well aware that staples having two ou more prongs and having headsof various fou mations are old. Therefore I do not make claim to suchstaples; but

W'hat I do claim, and desireto secure by l 2. The staple A, hereindescribed, consistA ing of the enlarged head A and prongs a', said headhaving concave deflecting surfaces or dies formed on its under side atright angles to the prongs, substantially as shown andl set forth.

3. The method of fastening, consisting in inserting the prongs of thedieheaded staple,

herein described, through the 'fabric or mate` rial at right angles toasimilar staple inserted through the material from t-he opposite sidethereof, the ends of theV prongs being then clinched beneath the headsand against the dies of the staples, all substantially as shown and setforth.

In testimony whereof I. have affixed my sigl nature in presence of twowitnesses.
